Bug description:
Impact
------
A memory leak that will cause Shotwell process to increasingly eat
memory constantly during a slideshow.
Test case
---------
*Start Shotwell and import a folder with about 10 photos; End
Shotwell.
*Save this script and execute it:
--->
#!/bin/sh
shotwell &
pid=$!
statm=/proc/$pid/statm
time=0
inc=1
version=$(dpkg-query -f '${Version}' -W shotwell)
while test -e "$statm"; do
#https://www.kernel.org/doc/html/latest/filesystems/proc.html
stack=$(cut -f6 -d' ' "$statm")
printf "%s %s\n" "$time" "$stack"
sleep "$inc"
time=$((time+inc))
done > "$version.dat"
<---
*Press F5 to start slideshow and keep pressing right arrow to cycle
through the photo set about 3 times.
*End Shotwell.
Expected: The memory logged in the *.dat file stops increasing instead
of steadily and indefinidetely increasing.
You can use "xmgrace -legend load *.dat" to get a plot of the behavior
before and after the fix for easier visualization (see attached
shotwell-stat.png).
Regression potential
--------------------
The changes are on a function that causes the Pixbuf cache to be
regenerated and the UI updated, so it should suffice to observe that
images are loaded alright in the slide show.
